Päikese aktiivsuse aruanne
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.
Päikese ja geofüüsikalise aktiivsuse aruanne 1997 Dec 11 2200 UTCValminud NOAA © SWPC ja töödeldud SpaceWeatherLive.com-iga
Ühine USAF / NOAA päikese- ja geofüüsikaalase aktiivsuse aruanne
SDF number 345 Välja antud 2200Z kuni 11 DEC 1997IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 10-2100Z kuni 11-2100Z SOLAR ACTIVITY WAS VERY LOW. SEVERAL OPTICALLY
UNCORRELATED B CLASS X-RAY BURSTS AND MINOR RADIO SWEEPS OCCURRED
THROUGHOUT THE PERIOD. REGION 8119 (N32W38) CONTINUES TO EXHIBIT
SLOW GROWTH AND IS NOW A 15 SPOT DSO BETA GROUP. NEW REGION 8122
(N31W06) WAS NUMBERED TODAY AND DEVELOPED IMPRESSIVELY INTO AN 18
SPOT DRO BETA GROUP. THE REMAINING REGIONS WERE QUIET AND STABLE.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO BE
VERY LOW TO LOW. REGION 8119 HAS POTENTIAL FOR ISOLATED C-CLASS
FLARING. ISOLATED C-CLASS ACTIVITY IS ALSO POSSIBLE IN REGION
8122. IF THIS REGION CONTINUES TO DEVELOP, ESPECIALLY AT ITS
PRESENT GROWTH RATE, IT MAY SOON BE CAPABLE OF PRODUCING M-CLASS
ACTIVITY.
IIA. Summaarne geofüüsikaline aktiivsus 10-2100Z kuni 11-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE. THE DISTURBANCE, WHICH
BEGAN YESTERDAY, IS STARTING TO SUBSIDE. THE FIELD IS NOW AT
PREDOMINANTLY QUIET TO UNSETTLED LEVELS. THE GREATER THAN 2 MEV
ELECTRON FLUX REACHED HIGH LEVELS LATE IN THE PERIOD.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED. HIGH LATITUDES MAY EXPERIENCE
ISOLATED PERIODS OF ACTIVE CONDITIONS.
